Hi Lez, Thanks a lot for the info. The number of I/O lines should not be reduced by programming one of the EPM7128s, unless perhaps the number of writes has exceeded the design limit (100), I guess anything could happen then, but, without more details, it sounds more like a case of "pilot error...

Re: MTX512 loading information required.

Hi, Welcome to the forum. As you might imagine, loading from tape files these days is a real pain.

Re: MTX User Community - The way forward

Well folks, the results are in! Or rather, the 7 poll responses have been duly considered and, by an overwhelming majority, the motion is carried! To summarise, Facebook will stay, but only as a "chatroom", the Forum is to be used for all detailed technical discussions, questions, problems...

Re: Scans of CPM disks

Hi Paul, don't expect too much, but you can get the four disk labels that I have here . . . http://www.primrosebank.net/computers/cpm/cpm_mtx_images.htm The CP/M System and Supercalc disks were in Memorex sleeves, if you click on the thumbnail, you can get an overly large copy of the labels / sleeve...

Re: Scans of CPM disks
